To solve this problem, we need to use the formula for gravitational potential energy (GPE), which is GPE = mgh.

Here,
m = mass of the rock = 5 kg
g = acceleration due to gravity = 9.8 m/s² (approximately, as it varies slightly depending on where on Earth you are)
h = height = 30 m

Substituting these values into the formula, we get:

GPE = 5 kg * 9.8 m/s² * 30 m = 1470 J

However, this is not an option in the multiple choice answers. It's possible that the question assumes g = 10 m/s² for simplicity, which is often done in basic physics problems. If we use g = 10 m/s², we get:

GPE = 5 kg * 10 m/s² * 30 m = 1500 J

So, the answer is a) 1500 J.
